Abstract
A disc turbine inlet collects working fluid, introduces it into the rotor housing at a defined location and imparted at a defined injection angle with respect to the tangential motion of the discs in rotary motion. An injection angle within the optimum range delineated by this invention enables the working fluid to entrain stationary or slowly rotating discs into motion. The inlet design combines smooth sectional transitions and arcuate directional changes to minimize frictional losses. The inlet has a nozzle section which locates precisely into a receiving aperture of the turbine rotor housing.
